Many have also requested feedback. Sadly the news is not good. Herewith:-

declaimed the following:
Anyway, this PUG mtg is going to be an 'experience'.
(I'll try (almost) anything once!)
The only thing missing is capturing your PoV of the meeting (with
screens) as a video for later streaming on YouTube
Once the link was made, we addressed the entire mtg, briefing members on
the experiment and the possibilities if offers. Only thereafter was it
down to individuals or small groups (although I suspect everyone was
subjected to every word I uttered - not the best approach - must check...).
In this jurisdiction, every single person present would have had to
consent to the video. However, as it turned-out, such would have been
less than helpful. Sigh!
Feedback/Observations:
The PUG meeting/experiment did not go very well. To be fair, I think
that the live-demo gremlins were alive and well, and more responsible
than anything/anyone else, but...
(as I've always said to my staff, having learned from (bitter)
experience, start earlier than anyone else with enough time to test'
everything, in-situ, before we start. The mtg organiser is/was no tutor
of mine, is undoubtedly a busy boy, and may not have had prior access to
the room/computer/network/...!)
The first issue was difficulty persuading Zoom to link. In the end there
were two Zoom-s running at the other end, but we elected to leave-alone
not actually knowing which was hosting the connection.
This process is normally quite straight-forward, and I've not
experienced such before. Sadly, but a harbinger of what was to come...
Attempts to connect to AWS Cloud9 were completely fruitless. Whereas the
remote PC had no trouble, at the PUG, entering access information
resulted in nothing beyond 'the spinning wheel'.
Similarly, whilst we both managed to both log-in to PythonAnywhere, we
made it no further.
In the end, I was (reduced to) screen-sharing, and chatting with folk
about their projects.
(the purpose of the meeting - so, not 'all bad' then)
Aside:
I was interested to hear how one member is performing local development
and then 'parcelling-up' his Flask app into a "script". Each time he
wants to test 'on the web', the script builds a new Docker-instance.
Most of the Python, pip3, etc, is held within some cache (I'm not a
Docker-person). It all happens acceptably quickly - please see other
thread where we discussed VMs, containers, and Pyenvs...
Have not heard-back from the mtg organiser, since. Am hoping he is busy,
rather than upset...
Meantime, assuming that the host-machine was an older lap-top (based
upon screen resolution only), I tried further combinations of hardware
and network (beyond previous preparation-experiments), including
resurrecting an old Windows Vista lap-top (I use Linux) which first
needed its Firefox considerably updated (although that may have been AWS
Cloud9's demand rather than PA's - can't recall). Once that prerequisite
was in-place, no problems were experienced!
In any (other) combination of hardware, OpSys, networking, etc; I have
no trouble using PythonAnywhere or AWS Cloud9 between two computers,
including at the local public library (and through their
firewall/security/decency/etc filters).
Conclusion:
the local university's foibles were likely to have been the source of
our comms 'problems'.
What next?
- continue to narrow-down possible issues, with the meeting organiser
- more experiments*
- (possibly) consider other software choices (earlier in this thread)
- equip the host-machine with head-set
- better brief/prepare mtg participants in 'what to expect'**.
* A fellow list-member and I are planning further experiments, hopefully
this week. If you are also interested, please feel free to contact me
off-list...
** As mentioned earlier, "pair programming" and/or my attempt to
remotely support our PUG's Coding Evenings, require abilities AND
facilities to "verbalise", "share", and "swap". Yes it would (perhaps)
be best if one package delivered 'all', but as long as multiple tools
will work happily together, success is possible. The key though is to
realise the social side of pair-programming, a willingness to share
thoughts, communicate with each-other, etc. Thereafter to adapt to the
'remote' wrinkle. We haven't reached the point of being able to explore
such factors.
PythonAnywhere:
Have greatly appreciated the interest of one of their principals. Sent
them feedback, with observations, suggestions, and questions. Pending
response, it is likely that I will 'drop' that option. In the final
analysis, I don't think PA a tool for "pair programming"; particularly
not when compared with (say) AWS Cloud9 which offers a "chat" panel,

I would love to hear your outstream.write() side-track!
I am not Rhodri James, but you can just write strings to text files:
outstream.write("X: ") # note, includes the space separator
outstream.write(str(thing[0]))
outstring.write("\n")
You can also format the string before passing it to write (which is
probably what Rhodri meant by "do my own formatting", like this:
outstream.write("X: %7.2f\n" % thing[0])
or this
outstream.write("X: {0:7.2f}\n".format(thing[0]))
or (since Python 3.6) this:
outstream.write(f"X: {thing[0]:7.2f}\n")
There are of course many variants to all three methods.
That is indeed what I meant. I do enough random dumping of things to
files for debugging purposes that outstream.write() is second nature to
me now. I once even went as far as sys.stdout.write() before sanity
caught up with me ;-)

Web framework for static pages
Hi. After a long break, I'm starting to work with web development again, in my company Nidelven IT. http://www.nidelven-it.no I've used Zope and Plone since the early days, as well as other web systems / frameworks, Python-based, some PHP, Java etc. However, I would like to add another tool to my toolbox, another weapon to the arsenal.. Some customers would want static pages, and that's something I want to offer. What frameworks are there for generating static web pages in Python? What are the features of each? Thanks, Morten -- https://mail.python.org/mailman/listinfo/python-list

ANN: A new version (0.4.5) of python-gnupg has been released.
A new version of the Python module which wraps GnuPG has been released.
What Changed?=
This is an enhancement and bug-fix release, and all users are encouraged
toupgrade.
Brief summary:
* Fixed #107: Improved documentation.
* Fixed #112: Raised a ValueError if a gnupghome is specified which is not an
existing directory.
* Fixed #113: Corrected stale link in the documentation.
* Fixed #116: Updated documentation to clarify when spurious key-expired/
signature-expired messages might be seen.
* Fixed #119: Added --yes to avoid pinentry when deleting secret keys with
GnuPG >= 2.1.
* A warning is logged if gpg returns a non-zero return code.
* Added ``extra_args`` to ``import_keys``.
* Added support for CI using AppVeyor.
This release [2] has been signed with my code signing key:
Vinay Sajip (CODE SIGNING KEY) Fingerprint: CA74
9061 914E AC13 8E66 EADB 9147 B477 339A 9B86
Recent changes to PyPI don't show the GPG signature with the download links.An
alternative download source where the signatures are available is the
project'sown downloads page [5].
What Does It Do?The gnupg module allows Python programs to make
use of thefunctionality provided by the Gnu Privacy Guard (abbreviated GPG
orGnuPG). Using this module, Python programs can encrypt and decryptdata,
digitally sign documents and verify digital signatures, manage(generate, list
and delete) encryption keys, using proven Public KeyInfrastructure (PKI)
encryption technology based on OpenPGP.
This module is expected to be used with Python versions >= 2.4, as itmakes use
of the subprocess module which appeared in that version ofPython. This module
is a newer version derived from earlier work byAndrew Kuchling, Richard Jones
and Steve Traugott.
A test suite using unittest is included with the source distribution.
Simple usage:
>>> import gnupg>>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory')>>>
>>> gpg.list_keys()
[{...'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2','keyid':
'197D5DAC68F1AAB2','length': '1024','type': 'pub','uids': ['', 'Gary Gross (A
test user) ']},{...'fingerprint':
'37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A','keyid':
'0C5FEFA7A921FC4A','length': '1024',...'uids': ['', 'Danny Davis (A test user)
']}]>>> encrypted = gpg.encrypt("Hello, world!",
['0C5FEFA7A921FC4A'])>>> str(encrypted)
'-BEGIN PGP MESSAGE-\nVersion: GnuPG v1.4.9
(GNU/Linux)\n\nhQIOA/6NHMDTXUwcEAf.-END PGP MESSAGE-\n'>>> decrypted =
gpg.decrypt(str(encrypted), passphrase='secret')>>> str(decrypted)
'Hello, world!'>>> signed = gpg.sign("Goodbye, world!", passphrase='secret')>>>
verified = gpg.verify(str(signed))>>> print "Verified" if verified else "Not
verified"
'Verified'
As always, your feedback is most welcome (especially bug reports [3],patches
and suggestions for improvement, or any other points via themailing
list/discussion group [4]).
Enjoy!

But still cannot success. The #python channel always works for me. The best place to ask for help is to do what it says in the message you were given ... "For more information about registering on Freenode, ask #freenode. " Have you asked for help in the #freenode channel? /join #freenode and ask there, no registration is required to do that. Be sure to communicate in short, clear sentences. Then wait for someone to answer you. Do not leave the channel after asking for help, wait for at least an hour. Any person might answer you, and sometimes random people there make mischief. But the people who are "ops" in that channel are freenode staff. They will help you and they have admin powers. Sometimes depending on time of day or day of week the staff might be absent. If so, just wait a few hours and try again. -- https://mail.python.org/mailman/listinfo/python-list

set_cookie is used to add an individual cookie in an existing cookiejar.
You might want to have a look at
requests.utils.add_dict_to_cookiejar(s.cookies, json.load(...)) or
passing the result of requests.utils.cookiejar_from_dict ti the cookies
